CAR-AXLE-BOX LID.

SPECIFICATION forming part of Letters Patent No. 428,944, dated May27,1890.

Applicationfiled May 25, 1888- Serial No. 275,110. (No model.)

T0 at whom it may concern.-

Be it known that I, TILLARD PENNOOK, a citizen of the United States, anda resident of Minerva, in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in Covers forJournal-Boxes; and I do hereby declare that the following is a full,clear, and exact description of theinvention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification, and in which- Figure 1 is a side elevation of acar-axle box provided with my improved lid or cover. Fig. 2 is a frontelevation. Fig. 3 is a vertical sectional view showing the lid raised.Fig. 4 is a similar view showing thelid closed. Fig. 5 is across-sectional view. Fig. 6 is a detail view in perspective of the lidor cover, showing the spring properly adjusted. Fig. 7 is a longitudinalvertical sectional view of the same. Fig. 8 is a detail view inperspective of a modified construction of the lid or cover with thespring in proper adjustment, and Fig. 9 is a longitudinal verticalsectional View of the same.

Like letters of reference denote corresponding parts in all the figures.

My invention has relation to sheet-metal covers for car-axle boxes, moreespecially for railroad-cars; and it has for its object to so constructthe same as to prevent the dust from entering the box and settling uponthe lubricated parts, and, furthermore, in various other details ofconstruction, as will be hereinafter more fully set forth.

Reference being had to the accompanying two sheets of drawings, theletter A represents a lid or cover of a car-axle box, constructed,preferably, of sheet-steel, pressed or stamped into the form shown inFig. 5 of the drawingsthat is to say, a blank formed with an uppercentral swell or bulge a and a lower depression a, said depressionterminating in an offset or shoulder a at its lower end and a transverseslot a at its upper end, adapted to receive a spring B, the end ofsaidspring being seated in the depression a and bearing against the offsetor shoulder in the lower end thereof.

The letter C represents a car-axle journalbox provided with a centralperforated lug D, through which a transverse rod E passes, said rodbeing adapted to receive hinge-connections a a upon the upper edges ofthe lid or cover A, and having its end screw-threaded to receive alocking-nut F, for retaining the rod in its proper position.

WVhen the hinge-connections are properly adjusted upon the transverserod E, it will be seen that the upper end of the spring B will bearagainst the central lug D, and the pressure upon the spring will serveto hold the cover securely in place over the opening in the journal-box,and notwithstanding the severe j oltin g to which the cars are subjectedthe tension of the spring is sufficient to overcome the tendency whichthe cover may have to fly open, thus preventing all dirt and dust frombeing admitted in this way. It will also be observed that by having thespring beneath the cover and protected thereby it is impossible for anydust to enter from the top of the device, and at the same time byproviding the cover with the bulge or swell the spring is allowed freeplay or yielding motion. When it is desired to lift the cover for thepurpose of oiling or lubricating the parts, the spring will slide overthe central lug D, whereby the opening of the cover is effected with butcomparatively little effort.

Not only does my device possess the advantages above set forth, but italso possesses the further advantage of providing a spring which can bereadily removed when desired, as if it should become broken or otherwisedamaged, it can be replaced by another with little or no trouble, exceptso far as it is necessary in substituting a spring of the proper length.By the construction of the lid or cover the spring, as heretoforeexplained, may be adjusted and secured without the employment of anyfastening devices whatever, the offset or shoulder a and the pressureupon the spring being sufficient to hold the same securely in position.It will be further seen that my device is a great improvement over thecovers or lids which are provided with springs integral therewith,inasmuch as should such springs break the whole device becomesinoperative, whereas in my device, as stated, the spring may readily bereplaced by another.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- 1. As a new article of manufacture,the herein-described lid or cover for axle-boxcs, consisting of a blankpressed or stamped so as to form an upper central swell or bulge, and alower transverse slot terminating in a depression, substantially as setforth.

2. As a new article of manufacture, the herein-described lid or coverfor ear-axle boxes, consisting of ablan k pressed or stamped so as toform an upper central swell or bulge, and a lower transverse slotterminating in a depression, said depression provided with an endshoulder or oitset, substantially as set forth.

3. The combination, with a lidor cover for caraxle boxes, having uppercentral swell or bulge and a lower transverse slot terminating in adepression, said depression terminating i n an end shoulder or offset,of a spring adapted to pass through said slot and tobear against saidshoulder or oitset, substantially as set forth.

1'. The combination, with a lid or cover for car-axle boxes, havingupper central swell or bulge and a lower transverse slot, said slottcrminati n g in a depression, of a spring provided with a lug orshoulder adapted to bear against the shoulder formed upon the under sideof the cover by the lower depression, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereuntoafiixed my signature in presence of two Witnesses.
